The present invention relates to a cosmetic comprising an acrylonitrile-butadiene rubber (NBR) as a carrier of a cosmetic composition and, specifically, to a cosmetic comprising a foam carrier and a cosmetic composition loaded on the foam carrier, wherein the foam carrier contains an NBR, includes pores with an average size of 200-900 μm, and has a thickness of 1-50 mm, and wherein the cosmetic composition has a viscosity of 2,000-60,000 cps. The present invention has excellent filling ability, loading ability, and discharging ability with respect to the liquid-phase cosmetic composition, and thus facilitates carrying a liquid-phase cosmetic composition with low viscosity to high viscosity.
